真空冶金分离技术从破碎的电子垃圾中回收铅、镉等重金属是一种技术上可行的方法。为了进一步确定该方法的环境影响和安全性，本文对真空冶金分离系统环境中的重金属暴露、噪声和热安全性进行了评估。设施附近总悬浮颗粒物（TSP）和PM10的质量浓度分别为0.1503和0.0973 mg m−3。TSP样品中Pb、Cd和Sn的浓度分别为0.0104、0.1283和0.0961 μ m−3。健康风险评价结果表明，Pb的危害指数为3.25 × 10−1，Cd的危害指数为1.09 × 10−1。Cd经吸入致癌风险为1.08 × 10−5。危害指数和风险值表明，Pb和Cd不会对工人产生非癌性影响或致癌风险。噪声源主要是机械真空泵和水冷却泵。它们的噪音水平都在80分贝(A)以下。热安全评价结果表明，真空冶金分离系统采用循环水冷却和绝热措施后，系统表面温度均在303 K以下。本研究提供了真空冶金分离系统的环境信息，有助于促进真空冶金分离回收电子垃圾重金属的产业化。
Vacuum metallurgy separation (VMS) is a technically feasible method to recover Pb, Cd and other heavy metals from crushed e-wastes. To further determine the environmental impacts and safety of this method, heavy metals exposure, noise and thermal safety in the ambiance of a vacuum metallurgy separation system are evaluated in this article. The mass concentrations of total suspended particulate (TSP) and PM10 are 0.1503 and 0.0973 mg m−3 near the facilities. The concentrations of Pb, Cd and Sn in TSP samples are 0.0104, 0.1283 and 0.0961 μg m−3, respectively. Health risk assessments show that the hazard index of Pb is 3.25 × 10−1 and that of Cd is 1.09 × 10−1. Carcinogenic risk of Cd through inhalation is 1.08 × 10−5. The values of the hazard index and risk indicate that Pb and Cd will not cause non-cancerous effects or carcinogenic risk on workers. The noise sources are mainly the mechanical vacuum pump and the water cooling pump. Both of them have the noise levels below 80 dB (A). The thermal safety assessment shows that the temperatures of the vacuum metallurgy separation system surface are all below 303 K after adopting the circulated water cooling and heat insulation measures. This study provides the environmental information of the vacuum metallurgy separation system, which is of assistance to promote the industrialisation of vacuum metallurgy separation for recovering heavy metals from e-wastes.
